What is an Ovarian Cyst?

        
An ovarian cyst is a sac filled with fluid. Ovarian cysts form during the normal process of ovulation; these cysts are called functional cysts. Most functional ovarian cysts are small, do not cause symptoms, are constantly changing during the menstrual cycle and go away on their own.


In general, treatment options are watchful waiting and surgical removal, which are based on the type of ovarian cyst. Some ovarian cysts are not related to menstrual function. Neoplastic cysts are abnormal and usually cause pain. Most are benign, rarely are they malignant (cancerous). Most ovarian cysts that are cancerous occur in women over 50.


Women may experience abnormal bleeding, sharp abdominal pain, pain during intercourse, and pelvic pain if a cyst leaks fluid or bleeds. Large cysts that do not go away on their own within a few months may need to be removed by surgery. Most cysts that require surgery are persistent and larger than 4 cm. The extent and type of surgery that is needed will depend on the size of cyst, type of cyst, the patient’s age, the patient’s symptoms and the patient’s desire to have children.
